Prompt

Apply an Anaglyph Stereo effect using overlapping red and cyan image channels with small horizontal offsets. Vary the separation by apparent depth, producing recognizable doubled contours around foreground forms while keeping distant regions more closely aligned. Retain clear underlying detail and restrained neutral midtones. Keep the original subject and composition.

Paste it into LetzAI with your own image to apply the effect ↗

Identify

Red and cyan1 double contours; spatially visible through filter glasses.

Principle

Two perspectives are separated by color and each is directed to one eye.

Example

NASA: Stereo view of a typhoon.

Try it out

Compare true stereo shifting with simple RGB shift2.

Background

Color stereoscopic experiments date back to the 1850s; Rollmann described a color stereoscope in 1853. The anaglyph is a special form of stereoscopic representation: Two views are placed in different color channels, and specially filtered glasses separate them again for the two eyes. NASA demonstrates how this can be used to spatially examine cloud heights and landscape features, for example. Red-cyan is a common combination, but not the only one. The comparison with RGB shift is crucial: A decorative color shift replicates the same perspective. A true stereo anaglyph requires two matching views with spatially different shifts. The NASA example shown is a modern scientific application.

Distinction

Simply shifting the color channels of a photograph does not create correct, different perspectives.

Aftermath

Stereoscopy refers to spatial vision from two perspectives; anaglyph here refers to their color-separated encoding. The terms are not interchangeable.

Question

Why does a uniformly shifted red-cyan portrait often appear flat?

Show possible answer +

It often contains only two shifted copies of the same view; the objects lack different, depth-dependent parallaxes.
